200 W Jackson has an indoor bike room (with a pump and tool station) and a gym-- they both require a one time fee of $50 for access.
Also, they do free weekly happy hours on the top floor!
Bike valet service is wonderful. Drop your bike in a rack on your way to your office, and the service takes it away and locks it up. Call ahead a few minutes before you leave, and the service brings your bike back out to the rack, where you can pick it up and go.
The gym in the building is $120 per year. Yes, $10 per month. Includes towel service. But no other laundry. :-(
